Abstract (en)
A display rack comprises shelves and a base. Each shelf comprises a sensor mat comprising a lattice of load sensors. The base is configured for measuring a total weight, which includes weights of any objects positioned on the shelves. The system is configured for determining object addition or removal event data based on in time corresponding changes of: total weight measured at the base; and binary load status of multiple load sensors of a sensor mat of the display rack. A binary load status of a load sensor indicates whether the load sensor at least in part supports an object or not. The event data comprises: an object weight based on said change of total weight measured at the base; and an object support shape and an object location both based on said change of binary load status of multiple load sensors of said sensor mat of the display rack.
